As far as I'm concerned this isn't possible with CSS and HTML. I don't believe they could provide such a high level of interaction between an elemental style and cursor. I'm fairly sure if this were possible you'd need to use jQuery at the very least.
At the very least it would, I believe, take a lot of effort to achieve and not something a beginner would choose as their first project.
I could be completely wrong! You never know, but I don't think that's the case. Perhaps try some more in-depth googling.
